gramcracker - I alternate between carrots and pretzels (which you have to eat 53 for 100 calories!). I feel satisfied in my hunger and that's where it worries me. I know I shouldn't be feeling that full on 900 calories.
Hopefully I can add some peanut butter and/or whey protein to my smoothies.
I want to fill my calories, but I don't want to eat junk to reach it.
